The chemical degradation of synthetic azo dyes color index (C.I.) Acid Orange 7, C.I. Direct Orange 39, and C.I. Mordant Yellow 10 has been studied by the following advanced oxidation processes: Fenton, Fenton-like, ozonation, peroxone without or with addition of solid particles, zeolites HY, and NH4ZSM5. Spectrophotometric (UV/visible light spectrum) and total organic carbon measurements were used for determination of process efficiency and reaction kinetics. The degradation rates are evaluated by determining their rate constants. The different hydroxyl radical generation processes were comparatively studied, and the most efficient experimental conditions for the degradation of organic azo dyes solutions were determined.
通过以下高级氧化过程研究了合成偶氮染料色指数（C.I.）酸性橙7、C.I.直接橙39和C.I.媒染黄10的化学降解：芬顿法、类芬顿法、臭氧化法、添加或不添加固体颗粒的过氧单硫酸盐法、HY沸石和NH4ZSM5。采用分光光度法（紫外/可见光谱）和总有机碳测量来确定过程效率和反应动力学。通过测定速率常数来评估降解速率。对不同的羟基自由基生成过程进行了比较研究，并确定了有机偶氮染料溶液降解的最有效实验条件。
